FALL RIVER — A woman urinating on a sidewalk outside Latino's Cafe took offense to a man staring at her in the parking lot Thursday night, police said.

The two exchanged words, which quickly escalated into a fight that involved at least six people. During the brawl, a 43-year-old man was stabbed in the back and transported to Rhode Island Hospital, Fall River Police Detective JD Costa said.

Costa said he did not have information Friday on the stabbing victim's condition.

Fall River Police Officer Derek Beaulieu and other officers responded to the 200 block of Haffards Street around 10:35 p.m. Thursday.

According to Beaulieu's report, the stabbing victim was in a vehicle with two women, ages 21 and 44, outside Latino's Cafe, at 296 County St. The bar's front door has a sign letting people know the establishment does not have a public restroom.

One of the women exited the car and urinated on a sidewalk, and then she exchanged angry words with the man staring at her in the parking lot, Costa said.

The man threatened to get his sister, who was inside Latino's Cafe, to beat up the woman. The man's sister, who is described as a 6-foot-tall black woman, exited the bar and began fighting with the woman in the parking lot, Costa said.

At that point, the stabbing victim, his other female friend, and two Hispanic men joined the fight. The stabbing occurred during the brawl, but the victim was not sure who stabbed him, Costa said.

The suspects ran off before police arrived. The victims walked home to the 200 block of Haffards Street, Costa said.
